E-Commerce and Import Cost Workflow
Selling online or importing products requires knowing your full cost stack before you can price profitably. Many e-commerce sellers calculate product cost and marketplace fees but miss warehousing, packaging, inbound shipping, and customs duties. The tools in this cluster handle the complete landed cost calculation.
Amazon FBA: Know Your Real Margin Before You Source
Amazon FBA profitability depends on a fee stack that most sellers underestimate. Referral fees run 8-15% of sale price depending on category. FBA fulfillment fees are size and weight-based (roughly $3-15 for standard items). Monthly storage fees add up during slow periods. The Amazon FBA Profit Calculator estimates net profit per unit after the full fee stack — run this before sourcing, not after inventory arrives in a warehouse.
True Landed Cost for Import Businesses
Landed cost is the true per-unit cost of bringing goods to your warehouse or marketplace. It includes purchase price, inbound freight (ocean or air), insurance, customs broker fees, import duties, and any US-side handling. Missing any of these elements creates pricing errors that destroy margin on high-volume products. The Landed Cost Calculator captures all inputs and shows total cost per unit and as a percentage of selling price.
Navigating US Tariffs in 2026
The 2025-2026 tariff environment significantly increased costs for businesses importing from China, Mexico, and other countries subject to elevated duties. The Tariff Impact Calculator estimates the duty rate and absolute cost increase for specific product categories. The Tariff Price Impact Calculator helps model whether to absorb the increase (reduce margin) or pass it through to customers (risk volume loss) — a critical decision with no universal right answer.
Frequently Asked Questions
What are the main Amazon FBA fees I should calculate?
Referral fee (8-15% of sale price, category-dependent), FBA fulfillment fee (weight and size-based, $3-15 for most standard items), monthly inventory storage ($0.78-$2.40/cubic foot, higher Oct-Dec), and long-term storage fees (6+ month items). Don't forget inbound shipping cost per unit when calculating total cost.
What is the de minimis threshold for US imports?
The US de minimis exemption has been a $800 threshold — imports valued below that were generally exempt from duty. However, exemptions from China and Hong Kong were eliminated in 2025, and the threshold rules are subject to ongoing policy changes. Check current rules before relying on de minimis treatment for any import-dependent business model.
How do I calculate the true landed cost of an imported product?
Landed cost = product cost + inbound freight + insurance + customs broker fee + import duties + domestic freight + any storage. A $10 product from China with $2 freight, $0.50 insurance, $1 broker, and $1.50 in duties has a $15 landed cost before you add Amazon fees, your own margin, or US shipping to customers.
Are Etsy fees higher than Amazon fees?
Etsy's fee structure is: $0.20 listing fee per item (renewed every 4 months or on each sale), 6.5% transaction fee on the sale price, 3% + $0.25 payment processing fee, and an optional Offsite Ads fee of 12-15%. Total fees on a $30 item are typically around $4-5, or 13-17%. Amazon's fees vary more by category but often run 20-30%+ for marketplace sellers using FBA.
How do I estimate EU customs duty for a product?
EU customs duty is based on the Combined Nomenclature (CN) HS code and country of origin. Duty rates range from 0% for some goods to 12-17% for others. VAT is then charged on the customs value plus duty amount. The EU Customs Duty Calculator estimates both based on product category, origin, and declared value.
